Untangler Rake Reviewhttp://tinyurl.com/lwgtgw4 Untangler Rake Great for grooming long, thick or double coated pets.Features extra long, solid metal rotating teeth.Where conventional rigid teeth would tend to drag hair from the root, the rotating teeth make grooming easy and healthy.Great for cleaning out undercoat when dog is shedding or blowing coat.Works well for collies, chows, keeshounds, etc.
